① The deoxidation method is designated as follows: GF = Fully killed steel containing nitrogen binding elements in amounts sufficient to bind the available nitrogen and having a fine grained structure.
② If sufficient N-binding elements are present, the minimum total Al content does not apply.
③ The total sum of Cr, Cu and Mo shall not be higher than 0,60 %.
